Structured Light Matching Of A Set Of Curves From Two Cameras

Patent No. EP3102908 (titled "Structured Light Matching Of A Set Of Curves From Two Cameras") was filed by Creaform on Feb 4, 2015. The application was issued on Dec 12, 2018.

Patent Summary

A method for matching points between two images of a scene using a structured light stereovision system with two cameras and a light projector unit. The system projects a pattern of non-crossing curves onto the scene, and the cameras capture images of the projected pattern. The method matches points between the two images using a figure of merit that evaluates the quality of the match, and discards matches that fail to meet a threshold. The method can be repeated for multiple frames to generate a 3D point cloud, and the position of the sensor can be estimated using targets, scene geometry, or texture.
